It is shown that the construction of dynamic compact thermal models for nanoscale devices, based on solution of the hyperbolic (wavelike) heat transport equation, can follow essentially the same approach as the authors analytical thermal impedance matrix method for the parabolic (diffusive) equation. The physicality of the hyperbolic equation is discussed in the light of calculated results. The analytical impedance matrix method for the time-independent case is employed in a thermally self-consistent device Monte Carlo simulation, illustrating the potential for detailed study of nanoscale electrothermal effects 关键词: heat conduction;high electron mobility transistors;hyperbolic equations;impedance matrix;Monte Carlo methods;nanoelectronics;parabolic equations;SCF calculations;semiconductor device models;nanoscale electrothermal simulation;self-consistent simulation;hyperbolic heat transport equation;nanoscale devices;dynamic compact thermal models;analytical thermal impedance matrix method;parabolic equation;diffusive equation;thermally self consistent device;Monte Carlo simulation;nanoscale electrothermal effects;HEMT
